BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates generally to a resistance training exercise device and method, and more particularly, to a resistance training exercise device and method employing interchangeable handles and straps for facilitating a variety of different exercises regardless of location.

2. Description of the Background Art

Resistance training is a popular form of exercise. Resistance training exercise devices known consist of a stretchable tube or cord with a pair of handles secured to opposing ends of the tube. To use this type of device, the user holds the handles and repeatedly stretches the tube, increasing the tension force in the tube, and retracts the tube while maintaining tension in the tube. However, resistance training devices such as these are very limited in application and structure.

The problem with conventional resistance training tubes is that the handles are connected the tube. For instance, U.S. Pat. No. 5,800,322, issued to Block, discloses an exercise device having a stretchable and elongated tube with a pair of handles secured to respective ends of the tube. As the handles arc secured directly to the tube, the tube can only be used with those handles and cannot be replaced with different handles or straps or secured to a stationary object, such as a door knob or wall hook, to accommodate a variety of exercises. In addition, if the handle or tube breaks the entire device must be replaced. Moreover, connecting a handle directly to a tube raises structural integrity issues. If a resistance training exercise cord device and system existed that accommodated the universal use of a plurality of different handles and straps with interchangeable cords of varying levels of elasticity to change the work load, it would be more cost effective and versatile compared to conventional devices and, hence, well received. Unfortunately, there are no known resistance training exercise devices or systems that effectively and adequately meet these parameters. Accordingly, there exists a need for such a device and system. The instant invention addresses this unfulfilled need in the prior art by providing a resistance training exercise device, system and method as contemplated by the instant invention disclosed herein.

In light of the foregoing, it is an object of the present invention to provide a resistance training elastic cord device having a plurality of interchangeable handles and straps.

It is also an object of the instant invention to provide a resistance training elastic cord device having a tethered clip for interchanging handles, straps, bars, ropes and, or other components.

It is another object of the instant invention to provide a resistance training elastic cord device having a clip tethered at each end of the cord for interchanging handles and straps.

It is an additional object of the instant invention to provide a resistance training elastic cord device having a clip tethered to each end of the cord by a structurally reinforced tether secured to each end of the cord.

It is a further object of the instant invention to provide a resistance training elastic cord system having a plurality of interchangeable cords of varying elasticity, handles and straps.

It is yet another object of the instant invention to provide a method for using the resistance training elastic cord system for providing resistance exercise to enhance muscle strength and tone.

It is yet an additional object of the instant invention to provide a resistance training elastic cord device and system that is cost effective and convenient to use.

In light of these and other objects, the instant invention provides a resistance training exercise device, system and method comprising at least one elastic, elongated and hollow cord with a tether secured to each end of the cord and a clip secured to the free end of each tether. The cord comprises a rubber or rubber like material having a predetermined level of elasticity. It is the level of elasticity that dictates the tension force of the cord in pounds. Accordingly, the cord is assigned an average workout weight in pounds, which is marked on the cord's corresponding clip. Each tether is secured to their respective end of the cord by a grommet, plug and sleeve. The plug is inserted in each cord end to prevent the grommet from slipping off the cord. The sleeve fits around the plug and the end of the cord containing the plug. The sleeve may comprise a separate component or the end of the cord folded back over itself and the plug. The clips preferably comprise an o-ring that receives the free end of the tether and a spring-loaded biasing flange for clipping onto a handle, strap or the cord itself. The handles and straps each comprise an o-ring for clasping by the clip. The handles are preferably covered with foam for comfort. Likewise, the straps are preferably padded for comfort.

The system of the instant invention preferably comprises a plurality of cords with a clip tethered to each end, plurality of handles, and plurality of ankle or wrist straps. Each cord comprises a different level of elasticity or tension force measured in pounds for facilitating a desired workout. Each cord is preferably color coded to indicate the “weight” of the cord. The system of the instant invention may further comprise a travel bag, user manual, workout guide and, or training video or DVD.

The method of resistance training in accordance with the instant invention comprises various exercises utilizing one or more cords and one or more handles or straps. The handles are used for stretching the cord with the hands. The straps are mounted to the wrists, ankles or stationary objects for stretching the cord. The user first determines the exercise to be performed. The user may reference the manual and guide for determining and designing exercise routines. Based on the exercise, the appropriate cord and handles or straps are selected and clipped to the tether or a clip may be clipped to the cord. Once the cord is properly prepared, a variety of exercises may be performed by stretching the cord and slowing retracting the cord to controllably release tension. For instance, the user may grasp a handle with each band and stretch and slowly retract the cord across the chest, or stand in the middle of the cord and stretch the cord upward and outward. The user may clip one end of the cord to a door handle or hook and grasp a handle at the other end with one hand for repeatedly stretching the cord by pulling outward. The user may clip one end of the cord to a door handle or door anchor device and secure an ankle strap to the cord at the other end and place it around an ankle for repeatedly stretching the cord by moving the leg outward. The cord may be secured to a stationary object at one end by wrapping it around the stationary device and clipping it to itself.

In accordance with these and other objects, which will become apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings.
